Oh, I tried that but it didn't seem to work, is the cheat code the text after CheatCodes in the text file name?
Mmmm... How weird, yet interesting behaviour. Have you tried to input the code when there's no text box in the screen after her first request?
The cheat code should begin to display on the top left corner of the screen when you input the second letter of the word, that way you should know that it's working.
Btw, the cheat code is the four lettered word that makes a reference to a specific typographic cousin of the seriff that appears before the - Effect inside the text file.
Hope that helps, or at least makes a little bit of sense -(8)-
